A Novel Concentration Device for the Detection of Food Pathogens
Nature published in July 2017, an article byGwangseong Kim, Horatiu Vinerean & Angelo Gaitas on a simple novel device to concentrate and detect food pathogens (immunocapturing method). The technique has the potential of being used for both clinical applications and food testing. System Set-Up The technique employs polymer (polydimethylsiloxane) tubes (1.02 mm in diameter) coated with an antibody. The test sample is circulating through the antibody coated tubes. The re-circulating of liquid media containing the bacteria through the antibody conjugated tubes result in the capturing of the pathogens by the conjugated antibodies. Several tubes can be used with different antibodies in each, thereby allowing the...
